AO 106: Application for a Search Warrant
AO 106, Application for a Search Warrant, is a United States District Court form from the U.S. Courts. The U.S. Courts page lists it under Law Enforcement, Grand Jury, and Prosecution Forms, effective on April 1, 2010, and the PDF prints the edition AO 106 (Rev. 04/10).
The form is written in the words of a federal law enforcement officer or an attorney for the government, who requests a search warrant and states under penalty of perjury which person or property is to be searched, what is concealed there, the basis for the search under Fed. R. Crim. P. 41(c), the code sections involved and the facts the application is based on. A judge signs below the line "Sworn to before me and signed in my presence." It is not a form a member of the public completes.
This page explains the form in plain words and is not legal advice. You can fill it out free in your browser on this page and download the result without an account.
